About the Airtac SC100 Standard Cylinder SC100X370
The AirTAC SC100X370 is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa, rising to 7068 N at the 0.9 MPa maximum operating pressure. With a 100 mm bore and 370 mm stroke, this model is built for medium-to-heavy linear automation tasks that need a robust push without stepping up to a larger footprint.
This cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 pneumatic ports. The adjustable air cushion at each end (29 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke shock. The body length A is 188 mm, giving a total extended length of approximately 558 mm. Standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X370 Is Used
Pallet Stop & Transfer
Provides the 3927 N push at 0.5 MPa needed to stop and transfer heavy pallets on roller conveyors, with a 370 mm stroke to span wide conveyor beds.
Press & Clamp Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large weldments or composite layups during assembly, with adjustable cushioning to protect tooling.
Bin Diverter Gate
The 370 mm stroke actuates large diverter chutes in bulk material handling, directing product flow between silos or packing stations with consistent, repeatable motion.
Is the Airtac SC100 Standard Cylinder SC100X370 the Right Cylinder?
Choose the SC100 when your load requires roughly 4000 N at typical plant pressure; if you need closer to 2500 N, step down to the SC80 (2513 N at 0.5 MPa). For strokes of 300 mm or more, like this 370 mm unit, be mindful of side loads—an unsupported 25 mm rod can bend under off-axis force, so consider an external linear guide or a guided cylinder if the load is not perfectly aligned.
To replace an existing cylinder, match five points: 100 mm bore, 370 mm stroke, PT port thread, any mounting accessory (this is a basic body, so order F-SC100LB, FA, FB, CA, CB, or TC separately if needed), and confirm whether a magnet is required (this model has no built-in magnet).
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC100 Standard Cylinder SC100X370 FAQ
At 0.7 MPa (7 bar) supply pressure, the SC100 bore generates 5497 N of push force on extension. The retraction (pull) force at the same pressure is 3681 N, reduced by the 25 mm rod area.
No. The SC100X370 is a double-acting cylinder and will not hold position when air is exhausted or pressure drops. The piston can drift or drop. If load holding is required, add a pilot-operated check valve or an external mechanical rod lock—the adjustable air cushion only decelerates the piston, it does not lock it.
